WHAT IS DUMORTIERITE QUARTZ:
Dumortierite Quartz is one of the rarer and more unusual blue varieties of quartz gemstones.
It is a gemstone-quality combination of quartz aggregate, intergrown with the mineral known as Dumortierite.
Dumortierite Quartz is one of the very few gem-quality varieties of blue colored Quartz. Most Blue Quartz is translucent to opaque, which means transparent materials should be tested for authenticity.
Dumortierite is a distinct mineral on its own. By composition, it can be easily identified as an aluminum borosilicate mineral.
Dumortierite Quartz color can resemble that of a few other popular blue gemstones such as Lapis Lazuli, Azurite and Sodalite.
However, Dumortierite Quartz is much harder and more durable than any other similar blue gemstone.
